L'application des IEs a été mieux acceptée politiquement et, très souvent, leurs effets se sont révélés plus incentifs que générateurs de revenus. En Suède, l'introduction des taxes écologiques a fait partie de la réforme fiscale générale alors que dans d'autres pays, l'approche s'effectue surtout au cas par cas. Les pays en développement peuvent tirer profit des expériences des pays Membres de l'OCDE avec les IEs, mais ils sont souvent confrontés à des défis ainsi qu'à des opportunités exceptionnels pour l'application de ces instruments. Historiquement, dans de telles économies, les prix des ressources naturelles et certains autres prix ont subi des distorsions et le rééquilibrage de ces distorsions est une des conditions préalables à l'utilisation efficace des IEs. Il faut également noter que les marchés sous-développés, les entreprises publiques ayant des contraintes budgétaires peu rigoureuses et des taux d'inflation élevés peuvent saper les effets d'incitation des IEs. Un fonctionnement satisfaisant des IEs exige : des droits de propriété bien définis et appliqués, une administration fiscale compétente et une acceptation politique générale du principe pollueur-payeur. Les économies en développement qui sont actuellement en phase de réforme structurelle devraient saisir l'opportunité d'introduire les IEs à un stage précoce de cette réforme ; cela favoriserait un alignement harmonieux entre les politiques économiques et environnementales. L'utilisation des instruments économiques (IEs) doit être échelonnée dans le temps selon l'évolution de la capacité d'application des gouvernements. Un ensemble de taxes appliqué de manière graduelle pourrait se présenter ainsi : suppression des distorsions de prix et des subventions préjudiciables à l'environnement ; identification et suppression des taxes et abattements préjudiciables à l'environnement ; examen des taxes existantes susceptibles d'être adaptées pour remédier aux problèmes d'environnement ; création de nouvelles taxes écologiques en réduisant par exemple d'autres taxes. Pendant une période de transition, le financement destiné aux améliorations de l'environnement pourrait être consolidé plus facilement si les revenus provenant des taxes et redevances sur l'environnement étaient affectés aux équipements de contrôle de la pollution, aux systèmes de contrôle et d'application des normes et enfin, aux budgets de recherche et développement consacrés aux technologies propres. SUMMARY In recent years, there has been a rapid spread of economic instruments (EIs) in environmental policies of OECD Member countries. The application of EIs has gained wider political acceptability and, in a growing number of cases, they have come to have incentive rather than merely revenue-raising effects. In Sweden, eco-taxes have been introduced as part of a broad fiscal reform, while in other countries the approach is more piecemeal. Virtually without exception, EIs are employed in combination with regulations and other policy instruments. Developing countries stand to learn from the OECD experience with EIs, but they often face unique challenges as well as opportunities in applying such instruments. Resource and other prices have historically been distorted in such economies, so correcting such distortions is a prerequisite to the effective use of EIs. Also, underdeveloped markets, public enterprises with soft budget constraints, and 2 high rates of inflation can all undermine the incentive effect of EIs. Requirements for the proper functioning of EIs include: well-defined and enforced property rights, an effective fiscal administration, and broad political acceptance of the polluter-pays- principle. Developing economies undergoing structural reforms should seize the opportunity to introduce EIs at an early date; this should permit a close alignment between environmental and economic policies. Economic instruments (EIs) need to be phased in over time as the implementation capacity of the government evolves. A time-phased "tax package" might be as follows: removing environmentally damaging subsidies and price distortions; identifying and removing environmentally damaging taxes or exemptions; examining how existing taxes may be adapted to address environmental problems; developing new eco-taxes, possibly while reducing other taxes. During a transitional period, financing for environmental improvements may be secured most easily through earmarking of environmental tax/charge revenues for specific investments in pollution control equipment, monitoring and enforcement, and research and development of cleaner technologies. 3 PREFACE There is a growing interest among developing economies — notably the dynamic non-Member economies of Asia and Latin America — to learn from the rapidly accumulating OECD experience with the use of economic instruments (EIs) in environmental policy. This paper, which draws upon substantial ongoing work at the Environment Directorate, provides some of the major lessons in a form readily accessible to developing country policy makers. It also highlights some of the specific challenges associated with applying EIs in a developing country context. The paper was originally presented at a Workshop held by the Development Centre in Hanoi, Vietnam, from 8 to 10 September 1993. That Workshop was intended to share with Vietnamese policy makers the findings of the Centre's research project on "Managing the Environment with Rapid Industrialisation: Lessons from the East Asian Experience" and represents an early example of a new thrust toward more active dissemination of the Centre's policy relevant research findings in developing countries. The Workshop was an instance of horizontal cooperation within the Organisation, as both the Environment Directorate and the Development Co-operation Directorate played an active role alongside the Development Centre. Jean Bonvin President OECD Development Centre December 1993 4 INTRODUCTION The evolution of environmental policies since the early 1970s in OECD countries has been characterised by two main features. First, the development of a number of “principles” designed to base these policies on firm and internationally recognised grounds; the “Polluter pays principle” is the most important one. Second, the development and deployment of so called “policy instruments” designed to implement and enforce environmental policies. I. THE POLLUTER-PAYS-PRINCIPLE (PPP) The PPP was first defined and recognised as an internationally agreed principle by the Organisation for Economic Cooperation and Development (OECD) in 1972 and defined as a principle whereby "the polluter should bear the expenses of carrying out the [ pollution prevention and control] measures decided by public authorities to ensure that the environment is in an acceptable state. In other words, the cost of these measures should be reflected in the cost of goods and services which cause pollution in production and/or consumption. Such measures should not be accompanied by subsidies that would create significant distortions in international trade and investment"1. In 1975 the European Community also defined the PPP as the basic principle for its environmental policy2. This definition highlights two key characteristics of the PPP: it is (i) a cost internalisation principle and (ii) an international principle. A cost internalisation

  • Appendix: Uk Cost Abatement Curve
    APPENDIX: UK COST ABATEMENT CURVE Summary The Task Force commissioned McKinsey to undertake what is currently the first comprehensive study of its kind for the United Kingdom. The study took as its starting point a previous McKinsey study on global greenhouse gas emissions. It then tailored that work to the UK, using a methodology developed over the past two years with the assistance of leading institutions and experts. A research team from McKinsey constructed a baseline forecast for UK emissions to 2030, drawing on a number of government and public sources. Working with Task Force members and other leading companies, the team then estimated the potential benefits and cost for over 120 different greenhouse gas abatement options that could help the UK meet its targets. These options were then represented in graphical form, illustrating the cumulative potential for emission reduction on the horizontal axis, and the cost per ton of emissions avoided on the vertical axis. This graph represents the first comprehensive UK marginal cost abatement curve. We do not expect this study to be the final word on how to meet the targets, and fully expect that further analysis will be necessary to guide policy choices. However, the level of detail obtained by this study is higher than anything produced before in the UK, and offers some important insights on the task that faces us. While considerable improvements have been achieved, the UK targets will not be met without significant additional effort. All abatement options must be considered if we are to meet the targets. Meeting the 2020 target will be extremely challenging, requiring nothing less than a full implementation of all the options.

Other forms of pollution are also common. • The noise of your neighbor’s party • The person smoking next to you • The mess in someone’s lawn Introduction 17 These outcomes are evidence of a market failure. • Markets are efficient when all transactions that positively benefit society take place. • An efficient market takes all costs and benefits, both private and social, into account. • Similarly, the smoker in the park is concerned only with his enjoyment, not the costs imposed on other people in the park. • An efficient market takes these additional costs into account. Asymmetric information is a source of market failure that we considered in the last chapter. Here, we discuss two further sources. 1. Externalities 2. Public goods Externalities 17.1 Externalities: A cost or benefit that affects a party not directly involved in a transaction. • Negative externality: A cost imposed on a party not directly involved in a transaction ‒ Example: Air pollution from coal-fired power plants • Positive externality: A benefit conferred on a party not directly involved in a transaction ‒ Example: A beekeeper’s bees not only produce honey but can help neighboring farmers by pollinating crops.
